Abstract
PURPOSE:To facilitate insertion of an electrode or heat emitting body of filament in a glass bulb and prevent interference of an exhaust nozzle etc., with the bulb ends at the time of jig insertion by specifying the distance between the two ends of a circular glass bulb to a certain range. CONSTITUTION:Distance l between the ends 1a, 1b of a circular glass bulb 1 is set to 30mm or more. This gap facilitates insertion of molybdeum foil 6 or heat emitting body of filament 5 into the bulb 1 and prevents interference with the two ends 1a, 1b at the time of jig insertion of exhaust nozzle etc., and a heat source or a lighting device can be easily formed which uses a circular glass bulb with good performance.
